ASoC: soc-pcm: use GFP_KERNEL when the code is sleepable
At the kzalloc() call in dpcm_be_connect(), there is no spin lock involved.
It's merely protected by card->pcm_mutex, instead. The spinlock is applied
at the later call with snd_soc_pcm_stream_lock_irq() only for the list
manipulations. (See it's *_irq(), not *_irqsave(); that means the context
being sleepable at that point.) So, we can use GFP_KERNEL safely there.
This patch revert commit d8a9c6e1f676 ("ASoC: soc-pcm: use GFP_ATOMIC for
dpcm structure") which is no longer needed since commit b7898396f4bb
("ASoC: soc-pcm: Fix and cleanup DPCM locking").
